Abstract base class for Record classes
Public interface
`‘Record’' is a widely used term in both programming languages and data structures to denote an imhogeneous set of fields. An alternative would have been to name it structure, which would have perhaps been a clearer name for C++ programmers.
RecordInterface denotes that this class defines the common interface to possible Record classes.
A Record is an heterogeneous, hierarchical, collection of named fields. The fields may be of scalar type, array type, a Table or a Record. This latter feature is what makes the Record a (potentially) hierarchical type.
RecordInterface is the abstract base class for various Record classes. At the moment three Record classes exist:
Presently, the scalar types are chosen to be compatible with the native types of the Table system, viz: Bool, uChar, Short, Int, uInt, Int64, Float, Double, Complex, DComplex, String. Arrays of all these types are also available. It is fairly straightforward to extend this set if necessary, although it will result in more template instantiations with the current implementation.
Each field has an integral index, which ranges between 0 and nfields() - 1
. The values of a field can be manipulated in two ways:
The structure of a record can be fixed or variable. If fixed, it is not possible to change the structure once the record has been instantiated. If variable, the record can be restructured or fields can be added/removed.
When a field gets added, it is possible to check if its name and type are valid by means of the CheckFunction callback. This is for instance used by the table system to assure that keywords and columns in a table do not have the same name.
Arrays in a record description can be fixed or variable shaped. If fixed shaped, only arrays with that shape can be stored in that field in the record. If variable shaped, any array can be stored.
However, note there is a difference between assign and define. Assign invokes the array assignment operator which checks for conformance. Thus even for variable shaped arrays, the new array must conform the exisitng one when using assign. Define simply replaces the array, thus for variable shaped arrays ay array shape will do.
RecordFieldPtr objects attached to a Record have to be notified when the Record is deleted or changed. The RecordInterface class provides the hooks for this via the Notice system. It is derived from NoticeSource. The class RecordNotice is for the messages.
This common base class provides a common interface to the various Record classes. Furthermore it is needed for the class RecordFieldPtr. Finally it provides the hooks for the notification in case the record structure changes.

typedef Bool casacore::RecordInterface::CheckFieldFunction(const String &fieldName, DataType dataType, const void *extraArgument, String &message) |
Define the signature of the add callback function.
This function is called when a field is added to the record (thus also when a Record is constructed from a RecordDesc). The function can check if the name and/or data type are valid. The extra argument is the argument given to the Record constructor which can be used to pass non-Record information. The function should return False if name or data type is invalid. In that case it can fill the message string, which will be added to the message in the thrown exception.
Definition at line 183 of file RecordInterface.h.
Define the Duplicates flag for the function merge in the various record classes.
This function merges the fields from that record (description) into this one. DuplicatesFlag determines what to do if a field already exists.

Define the flag telling if a Record has a fixed or variable structure.

Define a value for the given field.
Array conformance rules will not be applied for variable shaped arrays. If the field and value data type mismatch, type promotion of scalars will be done if possible. If not possible, an exception is thrown.
If the field does not exist, it will be added to the record. This results in an exception for fixed structured records. The field is checked by a possible field checking function before it gets added.

Int casacore::RecordInterface::idToNumber | ( | const RecordFieldId & | ) | const |
Get the field number for the given field id.
It throws an exception if id is unrecognized (e.g. an unknown name).

Is the Record structure fixed (i.e.
impossible to restructure or to add or remove fields)?

Make a unique record representation (for copy-on-write in RecordFieldPtr).
Implemented in casacore::TableRecord, and casacore::Record.
String casacore::RecordInterface::name | ( | const RecordFieldId & | ) | const |
Get the name of this field.
Referenced by casacore::RecordFieldPtr< T >::name().

Get the field number for the given field id.
It returns -1 if an unknown name was given.

RecordInterface& casacore::RecordInterface::operator= | ( | const RecordInterface & | other | ) |
Assignment (copy semantics).
This only assigns the RecordInterface object itself, thus not the data in a derived class. To do that the function assign
below can be used.

Remove a field from the record.
Caution: Removing a field means that the field number of the fields following it will be decremented; It will invalidate RecordFieldPtr's pointing to the removed field, but no other RecordFieldPtr's;
Implemented in casacore::TableRecord, and casacore::Record.

Change the structure of this Record to contain the fields in newDescription.
After calling restructure, description() == newDescription
. Any existing RecordFieldPtr objects are invalidated (their isAttached()
members return False) after this call.
If the new description contains subrecords, those subrecords will be restructured if recursive=True
is given. Otherwise the subrecord is a variable empty record. Subrecords will be variable if their description is empty (i.e. does not contain any field), otherwise they are fixed.
Restructuring is not possible and an exception is thrown if the Record has a fixed structure.

Set the comment for this field.
Implemented in casacore::TableRecord, and casacore::Record.
IPosition casacore::RecordInterface::shape | ( | const RecordFieldId & | ) | const |
Get the actual shape of this field.
It returns [1] for non-array fields.

Check if the Record has a non-fixed structure.
If it is fixed, it throws an exception. This can be used by other functions (like define).

Array<Bool> casacore::RecordInterface::toArrayBool | ( | const RecordFieldId & | ) | const |
Get an array while promoting the data as needed.
Int values can be converted to Bool. A scalar value is also converted to an array. These functions are slower than asX
, but more general.
